The Laboratory of Growth Regulators (LGR) was established in 1996 as a joint facility of the Institute of Experimental Botany of the Czech Academy of Sciences and the Faculty of Science of Palacký University. The purpose of the LGR is to conduct research in the field of molecular and physiological mechanisms of the action of growth regulators in living organisms and to develop the necessary technology. The LGR focuses on scientific research and teaching in the field of Experimental Biology, especially on the preparation of new growth regulators with potent biological activities, on the development of relevant analytical methods, and on the study of functions and effects on the growth and developmental process in cells, tissues, and whole organisms, including the development of drugs derived from plant hormones. Research into genes, the mechanisms that regulate their expression, and the development of mutant organisms with controlled gene expression are also included in the LGR’s scientific profile.
